Subject Re: Is it possible/easy to integrate cayenne with other frameworks?

Thanks - I've got to the point where Cayenne is trying to instantiate an 
instance of one of my pojos, but I've run into a problem... 

Cayenne *requires* the pojo to implement the Persisted interface, but 
this interface kills the Isis introspector (it detects the XMLSerializer, 
which contains a Collections parameter, which is not supported).

I'm looking into how to wrap the Isis user Pojo (which does not *have* 
to implement any interface or extend any class), into something that 
Cayenne can instantiate.

Any ideas?
